Susan Sarandon Wants to See a Woman on the $20 Bill—Who Do You Think It Should Be?

Who run the world? Girls (just ask Beyoncé)! So why isn't there a single woman on any piece of American money?

Susan Sarandon and fellow gender equality advocates not only want to know the answer to this, but they've proposed a solution: Women on 20s, a campaign determined to get one of 15 distinguished women to replace U.S. President Andrew Jackson on the $20 bill by 2020, the 100-year anniversary of the passage of the Constitutional amendment granting women the legal right to vote.

Sarandon helped propel the movement Tuesday when she tweeted a photo of herself holding cash. "I want to see a woman on the $20 bill," she wrote. "Post your own photo & join me by voting at womenon20s.org #WomenOn20s"

She went on to retweet other ladies holding up their $20s and demanding (social) change, using a #BadBitchesUnite hashtag as she did so. Sarandon also retweeted social media users from other countries proudly holding bills and coins with women's faces on them.

So what, exactly, is the game plan for Women on 20s? "It's our mission to generate an overwhelming people's mandate for a new $20 bill, to be issued in time for the 100th anniversary in 2020 of the Constitutional amendment giving women the right to vote," the organizations website states clearly. "Think of it as honoring the vote by casting your vote. The process of commissioning, designing and minting a new bill takes years, so now is a good time to act.

There are 15 potential candidates to be the new face of the $20, including Rosa Parks, Harriet Tubman, Margaret Sanger, Eleanor Roosevelt and Susan B. Anthony—wait a second...

The women's suffragist's likeness is on the silver dollar, but according to Women on 20s, "less than 800 million were minted before the public got sick of mistaking them for quarters." In 2000, Congress replaced Ms. Anthony's coin with a gold-colored dollar one depicting Sacajawea. Both ladies' coins remained in circulation, but as Women on 20s notes, "neither coin saw popular use, other than in vending machines and transit fare boxes."

Other important women have appeared on commemorative coins, none of which have been widely circulated as bills are.
